Onshore and offshore, EVERAXIS Slip Rings have proven their strength and reliability in harsh environments that may also be difficult to access, where maintenance must be reduced to a bare minimum.


Slip rings enable the transmission of data, power and signals on wind turbines between the fixed part, the nacelle, and the rotating part composed of the hub and blades.Today, more than 70,000 EVERAXIS slip rings are installed on wind turbines worldwide.EVERAXIS capacity to develop on demand custom solution with a shortened time-to-market is highly appreciated in this fast growing sector.

EVERAXIS proudly supports the key players and the most advanced platforms in Wind Energy technologies.


Pitch system: adaptation of the blade direction according to wind speed.
Pitch control: constant adaptation of the blade direction during operation of the wind turbine.
Blade heating system: prevention of blade icing and facilitation of wind turbine installation in colder areas.

Fiber Optic Rotary Joints


Integrated Fiber Optic Rotary Joints

EVERAXIS has more than 10 years of expertise in optical technologies for high data rate signal transmissions. Integrated Fiber Optic Rotary Joints (FORJ) can be supplied as a stand alone product with customized characteristics (wavelength, connectors, fiber characteristics) or combined into a hybrid opto electric slip ring with contact or contactless technology.

Integrated Rotating Systems


Opto Electrical Slip Ring (electrical and FORJ combined)

Opto Electrical Slip Rings are a combination of fiber optic rotary joints (FORJ) with gold, silver or carbon contacts. High data rates are transmitted through the FORJ while power and other signals are transferred through a contact technology.
